Paint preparation technology

Abstract

The invention discloses a paint preparation technology, which is characterized by comprising the technological steps of: (1) raw material selection, wherein by weight percent, polystyrene foam, phenolic foamed plastics, waste rubber and nitrocellulose account for 65%, industrial alcohol, coal tar, acetone and water solvent account for 15%, pigment and filler account for 15%, and a wet dispersing agent, a defoaming agent, a delustering agent and a plasticizer account for 5%; (2) fusion refining; (3) primary fining; (4) dispersing; (5) blending and color modulation; (6) filtering; (7) packaging. The technology disclosed by the invention is reasonable and compact, technological process is reduced greatly, paint source is wide, the technology belongs to waste reuse, and production cost is reduced; meanwhile, according to the raw material ratio, the technology is convenient for preparing various functional paints and can meet the requirement of production technology of the paints, dosage and ratio are accurate, deviation is small, product quality is guaranteed, and yield of enterprises is improved effectively.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a coating preparation technology. Background technique [0002] At present, coatings have been widely used in the construction industry, packaging materials, household daily necessities and automobiles and other fields. Paint is a chemical mixture that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. With the continuous expansion of industrialized large-scale production and the continuous improvement of people's living standards, some domestic garbage and industrial waste continue to increase, which has brought serious environmental pollution to the society. Waste and old foam plastics, waste rubber and coal tar have caused serious environmental pollution. Serious "white pollution" and "black pollution" have become a worldwide public hazard, endangering people's quality of life and restricting the development of the nation...

Problems solved by technology

Although most coating preparation processes are simple now, the process has great ambiguity, so the product coatings produced are highly polluting and the cost of raw materials is also high. For example, the application number CN200610015827.5 discloses a coating preparation process , put anhydrous coal tar and anhydrous phenol oil into the heating kettle, after stirring, add polyvinyl chloride powder, dioctyl phthalate, barium stearate, after stirring, heat, add talcum powder, keep warm, Stop heating, cool down, stop stirring, the advantages of the present invention: it has weather resistance, elasticity, elongation, cohesiveness, the coating film is not brittle or cracked at low temperature, and does not flow at high temperature, but there is no well-organized process Process, clear raw material ratio, in this kind of process, only one kind of coating can be produced, which is not suitable for the development of enterprises and the improvement of enterprise benefits
